IMPROVETIEN'I' IN MACHINE IOR 'SCOURING- AND BURNISHING- METALS.

The Schedule referred to in then: Letter! Patent and making part of the same.

Figure 3, second sheet, represents a side-view ele-p ration, showing the gear-wheel connections, 850.

Figure 4 shows an end view of the machine, with driving pulleys and gear.

Figure 5 shows the mode of constructing my burnishing-cylinder in a. sectional view through the same.

The object of my invention is to save manual labor in cleaning, securing, and burnishing sheet-brass and other metals.

My invention consists in the scraping and burnishing-cylinders, and the mode of constructing the same; also, in the arrangement and combination of the scourilng-brush, feed-rollers, scouring and burnishing-cyliners.

To enable others to make and use my invention, I will describe it more fully, referring to the drawings and to the letters marked thereon.

The frame A A may be made of timber or of metal, of a suitable height for the convenience of handling the sheet-metal, and may be made of any desired width and length for the required purposes.

The bottom of the table, which is under the scouring-brush O and the revolving scraper D, is movable, made so as to be taken out, or let down to discharge, and be cleaued'of the'stuff removed from the surface.

The frame A A is provided with two sets of feedrollers, a a and b b,"which are all geared together on the outside so as to carry sheets of metal uniformly through under the scouring-brush O, the scraper D, and, when desired, the revolving burnishing-cylinder E, which is mounted on the rear end of the machine.

The scouring-brush G-is incased with a sheet-metal cover, F, on the top of which is a hopper, G, in which sand or other material may he placed, and distributed stiffness to effect the purpose.

in any desired quantity, either wet or dry, for scouring, thecasc l preventing the dust from being thrown off and scattered about the premises.

The scraper-cylinder D is constructed by making combs d tl (l of sheet-steel, and inserting them in kerfs made in a roller, and securing them with caps H H, as shown-in fig. 5. The scraper-blades d (I may be two inches, more or less, in width, and of sufficient cylinder D are linngin movable boxes, so that the scraper-blades d (i can be brought to bear on .the metal when they become worn by use. p

The bmnishing-cylinder E is constructed in the same manner as the scraper-cylinder D, only the combplates or blades'e c c are of greater width, they being nine inches, more or less, so that they will spring and yield to the surface of the metal, they being curved so as to take a drawing stroke over the surface as it progresses forward, thus planishing and giving a greater brilliancy than can be produced by any other means that has yet come to my knowledge.

Duplicate scrapingand burnishing-cylinders may be so arranged to operate underneath those above de scribed as to scrape'and burnish both sides of plate or sheet metal at the same time, thus effecting a saving of one-half of the time and expense. of cleaning and finishing roll-brass, sheet-copper, zinc, sheet-iron, platesteel, or any composition of metal used in the arts or manufactures.

That I claim as 111 y invention, and desire to secure by Letters Patent, is-' 1. The'revolving scraper-cylinder D, as constructed, for scraping and cleaning sheet-metals, substantially as herein described.

2. The burnishing-cylinder E, for planishing the surface of metals, as and for the purposes herein set forth.

3. The feed-rollers an and b b, the scouring-brush O, scraping-cylinder D, and burnisher E, allcombined and arranged to operate in the manner herein de scribed, and for the purposes specified.
